Much of Urban's life is shrouded in mystery, leading to many myths and misconceptions. Despite the lack of sources he is the first Pope whose reign can be definitely dated. Two prominent sources do exist for Urban's pontificate: Eusebius' history of the early Church and also an inscription in the Coemeterium Callisti which names the Pope.
Urban ascended to the Chair of Saint Peter in the year of the Roman Emperor Elagabalus' assassination and served during the reign of Alexander Severus. It is believed that Urban's pontificate was during a peaceful time for Christians in the Empire as Severus did not promote the persecution of Christianity.
Due to the relative freedoms the Christian community had during Severus' reign the Church in Rome grew, leading to the belief that Urban was a skilled Converter. A Papal decree concerning the donations of the faithful at Mass is attributed to Pope Urban:
"The gifts of the faithful that are offered to the Lord can only be used for ecclesiastical purposes, for the common good of the Christian community, and for the poor; for they are the consecrated gifts of the faithful, the atonement offering of sinners, and the patrimony of the needy.
The location of Urban's burial site was shrouded in mystery for centuries after his death. It had been believed that he was buried in the Coemetarium Praetextati where a tomb was inscribed with his name. However when excavating the Catacomb of St. Callistus Italian archaeologist Giovanni de Rossi uncovered the lid of a sarcophagus which suggested that Pope Urban was in fact buried there. De Rossi also found a list of martyrs and confessors who were buried St. Callistus', which contained Urban's name. De Rossi therefore concluded that the Urban buried in the Coemetarium Praetextati was another bishop and Pope Urban was located in St. Callistus' Catacomb. While many historians accept this belief doubt remains. The basis for this is because Pope Sixtus III's list of saints buried in St. Callistus' Catacomb does not include Urban in the succession of Popes but rather in a list of foreign bishops. Therefore it is possible that Pope Urban is indeed buried in the Coemetarium Praetextati.
As no contemporary accounts of Urban's pontificate exist there have been many legends and acts attributed to him which are fictitious or difficult to ascertain the factual nature of. The legendary Acts of St. Cecilia and the Liber Pontificalis both contain information on Urban, although of doubtable accuracy.
A story that was once included in the Catholic Church's Breviary states that Saint Urban had many converts among whom were Tiburtius and his brother Valerianus, husband of Saint Cecilia. Tradition credits Saint Urban with the miracle of toppling an idol through prayer. This event is believed to have led to Saint Urban being beaten and tortured before being sentenced to death by beheading.
A further belief, now known as an invention from the sixth century, was that Urban had ordered the making of silver liturgical vessels and the patens for twenty-five titular churches of his own time.
